Somwhat of a misnomer seeming to mean a plant that completes a life cycle in two years. It actually is often applied to
plants that generally take more than one season or yearly cycle to complete a life cycle. Basically the term applies to plants
that die at the end of a life cycle (they die after they produce seeds) but don't complete that cycle in one season. Many
plants take an indeterminate number of years to complete the growth necessary to reproduce. See; perennial, annual, monocarpic
